The way customers connect to the information is an implementation detail. EMC provides choice and flexibility in how our customers are able to access and leverage their information assets. Most important, EMC assures the ability to manage, protect, and share those information assets … because that is our business! — EMC “EMC … fastest growing NAS vendor” — IDC 10/99 “NAS is often described as an alternative to storage area networks when, in fact, it is much more complementary … It looks like EMC is hitting the mark.” — Daniel Kunstler, JP Morgan “The more people that access information, the more valuable the information.” — Ruettgers’ Law
